Abstract

The effect of nano-kaolinite clay (NKC) on the early age cracking behavior of cement mortar was investigated. The restrained ring-test method was used to detect shrinkage crack tendency of cement mortar specimen. The cracking and strain on the surface of mortar ring for the ordinary and NKC mortar were monitored. The development of crack width and strain during the drying process were obtained. Finite element analysis is carried out to simulate the evolution of the crack in restrained concrete rings subject to circumferential drying. The results demonstrate that the addition of NKC increases the shrinkage cracking tendency of mortar at early age. It is found that the crack width is significantly increased in the mortar specimen added with 3% NKC replacement.
